Mixed-Signal Calibration of Pipelined Analog-Digital Converters

Least-Mean-Squares (LMS) based mixed-signal scheme for self-calibration of pipelined Analog-Digital Converter (ADC) is proposed. The technique uses an elegant continuous reference update algorithm to correct for gain errors and offset errors in a pipeline stage with minimal area and power overhead. Simulation results show the effeciency of the scheme for resolution of greater than 13bits in a CMOS process. Comments Copyright 2003 IEEE.
